Answer:
10,000 years
Explanation:
Given that,
Half life of the radioactive isotope, 
= 5000 years
Initial composition, 
= 16 grams
Final composition, 
= 4 grams
We know that,
Therefore, the age of the rock is 10,000 years.
<span>Jupiter moves faster than neptune in its orbit. It is because jupiter is closer to sun than neptune. The time taken to move on the orbit depends upon the distance from the sun. The length of orbit increases with increasing the distance from the sun and hence the speed also varies accordingly.</span>
1. The unknown is acceleration
2. The givens are the force(28,913N) and the mass(2350kg)
3. The equation is a=f/m where a is acceleration,f is force and m is mass
4.a=28913/2350 a=12.30340426
5. Therefore its acceleration is 12.30m/s²(rounded to nearest hundredth)
